Introduction

Census tracts were assigned a “vulnerability score” between 0 and 4, with a weight of 1 for each of the following that is true:

• Greater than XX% of households are renters
• Greater than XX% of the population are communities of color
• Greater than XX% of the population 25 years and older do not have a bachelor’s degree
• Greater than XX% of households have incomes at or below at or below 80% of the HUDadjusted median family income (MFI) [Note: HUD’s FY2015 MFI for the Seattle-Bellevue, WA HUD Metro FMR Area was $89,500.]

We defined vulnerable tracts as those with a vulnerability score of at least 3 out of 4.

Household earning less than 80% of the HUD , 2010-2014

This indicator is intended as a proxy for low-income households. There are many possible ways to determine whether a household fits this category, but one commonly-used metric is the area median income (AMI). Generally speaking, households earning less than 80% AMI are considered to be low-income households, as status which has implications for affordable housing eligibility.

The Lisa Bates used a fairly precise dataset for this indicator: percent of households that have incomes at or below at or below 80% of the HUD-adjusted median family income (MFI). The data source is HUD’s Consolidated Housing Affordability Strategy (CHAS) as used. Unfortunately, the most recent CHAS data is based on the 2009-2013 ACS 5-year estimate.

Rather than introduce an inconsistency in the observation periods of this assessment’s datasets, this method uses an approximation of the 80% AMI metric using the ACS Household Income (B19001), 2010-2014 5-year estimate. This data is structured as household counts within a range of annual household income (e.g. $15,000 to $19,999). The FY 2015 MFI Estimate for Seattle-Bellevue, WA HUD Metro FMR Area is $89,500. In inflation-adjusted 2014 dollars that is $87,732.78, and 80% of that equals $70,200; which puts it within the $60,000 to $74,999 range. Therefore, for this assessment any household with an annual income of $74,999 or less is considered to be low-income.
